I have a problem with a new Dell XPS 15 1050. After installation (or just using the live image) of 18.04 (and .1) and turning on WiFi, I get dramatic screen flickering every few seconds, especially when pulling data across WiFi. This includes bursts of coloured static for many seconds, artefacts, and the screen going black until a key is pressed.
I’ve tried multiple different combinations of graphics drivers with the same effects.
I have also tried Fedora with the same results.
I can’t understand why no one else seems to have had this problem. I’d suspect a hardware problem but Windows seemed to work OK. Any ideas appreciated.
